About me

I am a fourth-year Ph.D. student in Computer Science and Engineering at Notre Dame, where I work in the DM2 Lab advised by Prof. Meng Jiang.

My research focuses on building reliable LLM agents for real-world decision-making tasks that require multi-step reasoning over diverse sources of information. I work at the intersection of retrieval-augmented generation (RAG), tool-augmented language models (TALMs), and learning-based methods to improve agent behavior in imperfect and evolving environments.

More specifically, I study two themes: designing effective tool-use strategies and reliable task-specific tools for realistic data workflows, and improving agent frameworks with learning signals such as verifiability checks, tool outcomes, and consistency constraints. My goal is to make LLM agents more correct, robust, and efficient in dynamic settings.

Outside research, I am very much a cat person, which means I am easily distracted by cats on the internet and in real life 🐈. I am also a proud dad of two amazing cats: Mam (Fish Sauce) and Muoi Tieu (Pepper Salt).
